DAILY REPORT #1707
PERIOD COVERED: 0000Z (UTC) 08/28/96 - 0000Z (UTC) 08/29/96
Daily Status Report as of 242/0000Z
1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:
1.1 Completed WF/PC-2 6361 (High Resolution Imaging of X-Ray Selected =
AGNs)
The WF/PC-2 was used to make high resolution observations of the =
known low red shifted x-ray active galactic nuclius (AGN) MS1335.1-3. =
These data will allow a study of the optical properties of an unbiased =
sample of AGN host galaxies. The observations were completed as =
scheduled, and no problems were reported.
1.2 Completed GHRS/1 6828 (Far UV Emission Spectrum and Stellar Winds =
of Sirius A and Vega)
The High Resolution Spectrograph (Side One) was used to make far =
ultraviolet observations of the star Vega (aka, HD172167). The proposal =
text indicated the the Cycle #1 spectra reviealed unexpected presence of =
emission lines and a slight stellar wind. The observations were executed =
as scheduled, and no anomalies were noted.
1.3 Completed WF/PC-2 6253 (Pure Parallel Archive Program)
The WF/PC-2 was used to execute a pure parallel program taking =
ultraviolet observations running concurrently with prime science =
observations. The intent is to search for extra-galactic sources with =
flux excesses at 3000 A0 and galactic sources with excesses at 1600 A0. =
The observations were completed as planned, and no problems were =
reported.
1.4 Completed Five Sets of WF/PC-2 6634 (Nucleus of Comet =
46P/Wirtanen)
The WF/PC-2 was used to make a series of images of the inner =
nucleus of the periodic comet 46P/Wirtanen, which is a prime target of =
the Rosetta Rendezvous Mission. The HST data will provide color and =
rotational data on the nucleus of the comet. The observations were =
completed as planned, and no problems were reported.
1.5 Completed Two Sets of GHRS/1 6171 (CRIMP1: Cycle 5 =
Condensed-Regimen Integrated Monitoring Program)
The High Resolution Spectrograph (Side One) was used to obtain =
darks, internal flats (in photoscan mode), wavelength calibrations and =
observations of standard star BD+28D4211. This includes detector =
calibration, sensitivity monitoring, and wavelength monitoring. The =
observations were executed as scheduled, and no anomalies were noted.
1.6 Completed Two Sets of FOS/BL 6913 (FOS Cycle 6: Location of =
Spectra and Wavelength Calibration)
The Faint Object Spectrograph (Blue Side) was used to make a =
series of stability calibration measurements of the wavelength location =
and the location of the spectra. All the observations were internals. =
The observations were completed as planned, and no problems were =
reported.
1.7 Completed GHRS/1 6446 (The High Chromospheres of the late A Stars, =
Altar and Alpha Cephei)
The High Resolution Spectrograph (Side One) was used to make the =
observations of the Si IV lines in the high chromosphere of the late, A =
class, star Altar (aka, HD187642). These data will be used to construct =
a model of the chromosphere structure of this star. The observations =
were completed as scheduled, and no anomalies were reported.
